We have the 2022 Blade 15 (SKU RZ09-0421x). I got my son the Core X V2.0 for Christmas and it just refuses to work!
The current best I can do is to get the Core to see the Blade’s internal GPU. So many different things tried.
It all leads to one question.
Is Thunderbolt PCIe tunnelling disabled by firmware policy on SKU RZ09-0421x, and is there any firmware that enables it?
